Product Description SFP Series The DB1310/1550-SFP-SC.S20 is small form factor pluggable module for IEEE 802.3ah 100BASE-BX10 and OC-3/STM-1 SONET/SDH single fiber applications by using 1310 nm/1550nm(1550nm/1310nm) transmitter and 1550nm/1310nm(1310nm/1550nm) receiver. It is with the SFP 20-pin connector to allow hot plug capability. The transmitter section uses a multiple quantum well A type / B type laser and is a class 1 laser compliant according to International Safety Standard IEC 60825. The receiver section uses an integrated A type/ B type detector preamplifier (IDP) mounted in an optical header and a limiting post-amplifier IC. The DB1310/1550-SFP-SC.S20 are designed to be compliant with SFF-8472. Absolute Maximum Ratings *Note3 Parameter Symbol Min. Max.

Pull up voltage between 2.0V and VccT, R+0.3V. When high, output indicates a laser fault of some kind. Low indicates normal operation. In the low state, the output will be pulled to < 0.8V. 2) TX disable is an input that is used to shut down the transmitter optical output. It is pulled up within the module with a 4.7 10 KΩ resistor. Its states are: Low (0 0.8V): Transmitter on (>0.8, < 2.0V): Undefined High (2.0 3.465V): Transmitter Disabled Open: Transmitter Disabled 3) Modulation Absent, connected to VEET or VEER in the module. 4) LOS (Loss of Signal) is an open collector/drain output, which should be pulled up with a 4.7K 10KΩ resistor. Pull up voltage between 2.0V and VccT, R+0.3V. When high, this output indicates Page 7 of 11
the received optical power is below the worst-case receiver sensitivity (as defined by the standard in use). Low indicates normal operation. In the low state, the output will be pulled to < 0.8V. 5) VeeR and VeeT may be internally connected within the SFP module. 6) RD-/+: These are the differential receiver outputs. They are AC coupled 100Ω differential lines which should be terminated with 100Ω (differential) at the user SERDES. The AC coupling is done inside the module and is thus not required on the host board. The voltage swing on these lines will be between 400 and 2000 mv differential (200 1000mV single ended) when properly terminated. 7) VccR and VccT are the receiver and transmitter power supplies. They are defined as 3.3V ±5% at the SFP connector pin. Maximum supply current is 300mA. Recommended host board power supply filtering is shown below. Inductors with DC resistance of less than 1 ohm should be used in order to maintain the required voltage at the SFP input pin with 3.3V supply voltage. When the recommended supply-filtering network is used, hot plugging of the SFP transceiver module will result in an inrush current of no more than 30mA greater than the steady state value. VccR and VccT may be internally connected within the SFP transceiver module. 8) TD-/+: These are the differential transmitter inputs. They are AC-coupled, differential lines with 100Ω differential termination inside the module. The AC coupling is done inside the module and is thus not required on the host board. The inputs will accept differential swings of 400 2000mV (200 1000mV single-ended). EEPROM The serial interface uses the 2-wire serial CMOS EEPROM protocol defined for the ATMEL AT24C02/04 family of components. When the serial protocol is activated, the host generates the serial clock signal (SCL). The positive edge clocks data into those segments of the EEPROM that are not write protected within the SFP transceiver. The negative edge clocks data from the SFP transceiver. The serial data signal (SDA) is bi-directional for serial data transfer. The host uses SDA in conjunction with SCL to mark the start and end of serial protocol activation. The memories are organized as a series of 8-bit data words that can be addressed individually or sequentially. The Module provides diagnostic information about the present operating conditions. The transceiver generates this diagnostic data by digitization of internal analog signals. Calibration and alarm/warning threshold data is written during device manufacture. Received power monitoring, transmitted power monitoring, bias current monitoring, supply voltage monitoring and temperature monitoring all are implemented. If the module is defined as external calibrated, the diagnostic data are raw A/D values and must be converted to real world units using calibration constants stored in EEPROM locations 56 95 at wire serial bus address A2H. The digital diagnostic memory map specific data field define as following.for detail EEPROM information, please refer to the related document of SFF 8472 Rev 9.3. Page 8 of 11
